CAR-ROOF.

Specification of Letters Patent.

Patented Got. 1, 1918.

l 1 Application filed. July 8, 1918. Serial No. 243,768.

To all whom it may concern:

Be it known that I, FRANK W. VVoLrr, a citizen of the United States, and a resident of Parnassus, county of Westmoreland, and State of Pennsylvania, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

. My invention relates to car roofs and 1 more particularly to outside metal car roofs comprising a plurality of metal sheets movably mounted on the substructure. One of the. principal objects of the invention is to enable such roofs to accommodate the various distortions arising from the racking and weaving of the car and avoid buckling the roof sheets.

The invention consists in a roof sheet especially adapted for use at the ends of a car roof, and in the weatherproofing means for its outer margins. The invention further consists in the parts and combinations of parts hereinafter described and shown.

. In the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur,

Figure 1 is a plan View of an end portion of a car roof showing .my invention applied theretoj ,Fig. 2 is an end elevation of the upper portionof the car shown in Fig. 1;

Fig. 3 is a plan view similar to Fig. 1,the end sheet caps being removed, one of the roof sheets being broken away so as to disclose the caves and end flashings; a

Fig. 4. is an enlarged vertical longitudinal section through the hood casting at the ridge on the lin'e44 in Fig. 2;

- Fig. 5 is a detail end view of the end por tion of the car at the ridge, the hood casting being shown in section on the line 55 in Fig. 4;

Fig. 6 is a plan view of theend portion. of the car at the ridge, the portion'of the hood casting overlying the ridge ends of the end sheet cap being broken away;

Fig. 7 is a vertical cross-section through the end portion of the car near the ridge line on the line 7-1-7 inFig. 1; i

Fig. 9 is a vertical cross-section through the eaves portion of the car on the line 9--9 in 1. showing a means leeeely secur ing the eaves ends of the roof sheets to the roof substructure.

.The roof shown in the drawings comprises a wooden substructure consisting of roof sheathing boards 10 supported at their end on a side plate 11, one end only of the car being shown. Metal roof sheets 12 rest on the roof sheathing boards 10 and extend transversely of the car from caves to ridge. The ridgeends of abutting sheets are con nected by standing scams 1?). The sides of adjacent sheets are connected by standing seams 14;. The endmost roof sheets are cut obliquely or on the bias, the ridge end of each sheet being wider at the ridge than at the eaves. V i

1 Eaves flashings 15 of angle section rest in shallow grooves along the eaves edge of the car, their end portions being turned down over the eaves edge of the roof sheathing and nailed to fascia board 16. The caves flashings 15 have rebentportions 17 interlocking with the doubled under ends 18 of the roof sheets 12.

End flashings 19 of angle section, similar to the eaves fiashings, lie in grooves along the tops of the ends of the car. The vertical down-turned portion of the end flashing is secured to the end fascia 20 of the car in a manner similar to the eaves flashings .15. The inner marginal portions 21 .of the end flashings are doubled back substantially flush with the under sides of the endmost roof sheets. The outer marginal portions of the endmost sheets project beyond the doubled back portions'21 of the end flashings 19. Metal caps 22 of angle section are arranged on each side of the ridge seam, their horizontal portions overlapping the outside marginal portions of the end sheets. The vertical portions of the cap overhang the end of the car and are secured to the end fascia 20 by nails 23. The horizontal portions of the caps 22 which overlap the end flashing and the side marginal portions of the end sheets are wider at theeaves than at the ridge. The inner margins 24 of the horizontal portions of the caps are turned under and bear against the roof sheets. The vertical portions of the caps have corrugations 25 which stilfen them. These corrugae tions extend a short distance over the horizontal portions of the caps. The inner mardirt finding their Way into the car. A hood cap, 26, is preferably secured to the end :t'asci a 19 by nails 27,the hood portion of which straddles the open end of the ridge seam and also covers the meeting ends of the end sheet caps. The unavoidable relative movement between the roof sheets and, the sub-. structure, such as the diagonal movement of the roof sheets when the car is thrown out of square results in a greater amount of movement of the root'- sheets at the eaves than at the ridge. This movement ace-oinmodate'd Without decreasing the weatherproofing qualities of the roof by the wide orderlap of the end sheet and end sheet cap at the eaves of the car. The cutting of the end sheetsand the end sheet caps on the bias de creases the amount of material needed for these members.

The end sheet cap shown adapted for use with other styles of roof than the one described. It is evident that changes may be made Without departing from the invention and I do not Wish to be limited to the construction shown.

What I claim is: a

1. In a car-roof, an end sheet wider at the ridge than at the caves and .a cap for said end sheet, said cap overlapping said end sheet and being Wider at the eaves'than at the ridge.

2. In a carroof, an end sheet movably mounted onthe substructure, a cap for said end sheet, said cap being securedto the car and'having a portion overlapping said end sheet, themargins of the. lapping portions of theend sheet and cap. being cut obliquely, whereby the. lap between said end sheet and oapis. greatest at the eaves of the car.

3. In a car roof, a movably mounted end sheet, and a cap for said end sheet, said cap having a portion adapted to overlap the side outer margin of saidsheet, the lap between the end sheet and cap being greater at the eavesthan at the ridge of the car.

at In a car roof, end roof sheets movably mounted on the substructure: on each side of the ridge line of thecar, said sheets being connected by seams at theridge, and a cap securedto the car, a portion of said capwoverlapping the outsidexinargin of the end rootlsheets, the side margin or said end roof sheets adjacent to the end of the car being closer to the end of the car at the ridge thanrat the eaves.

5. In a car roof, an end sheet having its marginal portion adjacent to the can end stopping short thereof, and a" cap secured to saidcar, said cap having a portion adapted to cover said marginal portion of said roof sheet, said marginal portion of the end sheet opposite angles 011 each side of the ridge,

and a cap. secured to the car having a portion overhanging the marginal portion of' said end sheet and the manglnal portion of the overhaning portion of the cap being cut diagonally at opposite angles on each side of the ridge, the angle of the marginal portion of the cap being greater than the angle oi the marginal portion of the end sheet at each side of the ridge.

7. In a car roof, an end sheet, the marginal portion or said sheet adjacent the ridge elf-the car being cut diagonally from the ridgeto the eaves away from the-end of the car, and a cap securedto, thecar', said cap overlapping the diagonally cut marginal portion of the end sheet, whereby the capacity for relative inovement betvreenthe end sheet and the cap is greaterat the eavesthan at theridge.

8. In a car roofthe eornbinatienwith end roof sheets connected by ridge-seams and arranged on each side'of the ridge, a flashingrnember secured to said car beneat-h the end roof sheets, caps for covering the mare ginal portions of the end roofi sheets adjacent to the end of the ear, said CZtPS* .bGID secured to the end of the carateach side 0% the ridge seam, a hood cap secured tothe having a hoodv portion covering the end of theridge seam and it theadj acentridge ends of the caps, the end sheets being Wider at the ridge thanat the eaves and the end sheet caps being Wider at their eaves than at the ridge. l

9. A car roof, roof sheets movably mounted thereon on opposite sidesofthe'ridge and connected along the ridge by seams, spaced end caps overlapping the side outer margins lapping portions oh the end "sheet caps being cut obliquely from the ridge to the eaves, whereby the overlap between the side outerinarglnal portion of the end sheets and theend caps is. greater at tho eares than the ridge.
